Currently, blue light can be found everywhere. We have computers, televisions and smart devices that emit it constantly. Why is it bad for you? Keep on reading to find out.
A serious concern
There are some cases where blue light was a cause of developing accelerated blindness and eye disease. A new study performed at the University of Toledo tells us that by looking for a long time at digital devices we end up killing cells from our retinas. This, in time, leads to macular degeneration, an incurable disease which usually can be found in elders in their 50s or 60s.
A chemical reaction happens when we expose ourselves to blue light and our photoreceptor cells are ‘poisoned’. Once these cells die, they are gone, they don’t regenerate. But don’t worry, there’s a way to prevent all this.
A helpful ally
An assistant professor from the University of Toledo, responsible with the chemistry and biochemistry department, has found a type of molecule called alpha tocopherol. Ajith Karunarathne, the assistant professor told us that it is an antioxidant derived from vitamin E and apparently, it can stop the poisonous reaction.
When we get older it becomes harder and harder to fight eye disease. Researchers hope to use this antioxidant to help their research in finding preventative measures, maybe in the form of eye drops.
Enemy lurking in the dark
Blue light is particularly dangerous in the dark. This kind of scenario can lead to the appearance of cancer, diabetes, obesity and heart disease, according to a study performed at Harvard.
Apparently, there can be a connection between blue light and a decrease in melatonin, the hormone that controls our circadian rhythm, our human body clock. When that’s off, so is our blood-sugar levels and that’s where all sorts of problems appear.
